“AC” or Air Conditioner has become one of the important needs in each residence. For those of you who first wanted to buy air conditioning or for those who want to add a new air conditioner, you should read the troubleshooting tips below as a reference or consideration before selecting an AC which is how that is suitable for Your Home
BTU (British Thermal Units)
Usually the amount of air conditioning units are calculated from the BTU (British Thermal Units), the higher the BTU the bigger room that can be “cooled”. While in Indonesia, many of which often use the unit “PK” but most of this one unit less representative to calculate the AC needs to be used.
When you buy with a BTU air conditioner that is too large, not just a matter of money and waste of electricity but also can interfere with health (such as moisture problems are not well / dry).
So how to know the BTU big do we need? The simplest way is to use this simple formula is P (length of the room) x L (room width) x 500 and the result is the amount of BTUs you need, such as your room is     3 x 2 m, BTU is 3 x 2 x 500 = 3000 BTU.
Calculate the power capacity. For example, the AC in the room bedroom 1 PK Brand X has a capacity of 10,000 Btu / h and 1200 watts of power consumption. According to conversion unit,    1 PK = 2544 Btu / h = 746 watts.

Choose AC which have a converter
Converter in AC function to adjust the electrical load, an automatic air conditioning will reduce the cooling load but still in position on (on). As we know the largest electric power at the start.
Consider additional features useful for health.

There is now conditioned by the features that can eradicate the bacteria. There was even able to filter out very fine dust particles including bacteria. In addition, there is also air conditioning that offers a feature to kill germs and remove unpleasant odor like the smell of cigarette smoke and features of vitamin C filter that contains antioxidants to boost immunity for the body becomes more healthy and fresh.

Eficiency Energy Ratio (EER)
Next to consider is the level of efficiency. On the AC there are energy eficiency ratio (EER). Should the user choose a high EER levels, because high EER showed low electrical power. In Europe there are standards regarding the EER, is generally the best AC has a high ratio above 10. “EER level also determines the price, the higher the more expensive, because more power-efficient, smaller EER is more extravagant
In addition, you also have to look at the technology embedded in the AC. “I think you should choose the technology compared to the conventional inverter

Specify brand of air conditioning and do not be tempted by cheap prices
In determining the brand, we do not be tempted by the cheap purchase price. Because in the market we will find AC ½ PK particular brand which only 340 Watt power consumption, while other brands AC ½ PK 800Watt power consumption.
Of course AC ½ first PK 340 Watt consumption of which only the purchase price is more expensive than the second. But if we want to calculate the difference in price with the cost of electricity which required, we will think back to choose it  on the market.    Example   :
AC ½ PK brand A 355Watt power consumption with the purchase price $300
AC ½ PK B brand 800Watt power consumption with the purchase price of $200
Two of them have the same capacity that is 5000btu / h

If we only look at the price we would choose AC B is cheaper.

But if we want a little arithmetic, the difference in power consumption of 800w-355W = 445 Watt we have to pay more expensive every month. If we assume AC is turned on 10 hours a day and the price per kWh PLN = USD 500, – (tariff goals. R1-2200), then we have to pay per day 0.445 kWh x 10 hours x $ 500, – = $0.25, – more expensive.

Thus within a month we pay 30x$0.25, – = $7.5, – a pretty fantastic amount not ….??

Selecting the type of AC.

Based on the type there are 4 types of air conditioners are often used in household yatiu split, window, cassette and Standing AC. 1) Type of Split AC separates the ‘space within’ (indoor) with the ‘outer space’ (outdoor). Noise is generated when the cooling work becomes softer because they are separate. Suitable for a room that needs peace, like the bedroom, den or library. 2) Type AC Window, usually put the indoor and outdoor united position in the opposite side. Usually chosen because of limitations of space considerations, separator on flats. And because of its usually large, the type of AC is relatively more secure from theft. 3) Cassette type air conditioner, tend to be more difficult in the installation. Normally suitable for incorporation in a high rise building (storey). 4) Standing AC. Type AC is suitable used for the activities of situational and mobile because its function is easily removable, such as seminars, lectures etc. outdoor.
